PRINTING DEVICE FOR PAPER-ROLLS.

SPECIFICATION forming part of Letters Patent No. 747,580, dated December22, 1903. Application filed October 28,1899. Serial No. 735040. (Nomodel.)

To aZZ whom it may concern:

Be it known that I, JA ES W. BOLGER, a subject of the Queen ofGreatBritain, residing at Stratford, in the Province of Ontario, Canada,have invented certain new and useful Improvements in Printing Devicesfor Paper-Rolls,of which the following is a specification.

My invention is especially designed for attachment to aWrapping-paper-roll holder to receive the paper therefrom evenly andtruly at all times regardless of the variable size of the paper-roll,which may be readily adapted to various widths of paper and in which theprinting-roll will always make a properlyregulated impression upon thepaper.

To these and other ends hereinafter apparent my invention consists incertain details of construction fully set forth in the followingspecification and claims, reference being had to the accompanyingdrawings, wherein- Figure l is a perspective view of my improved deviceapplied to a wrapping-paperroll holder; Fig. 2, a vertical sectionalelevation in line a; a: of Fig. 3 when the printing device is in itsworking position; Fig. 3, a front elevation of the upper part of arollerholder frame with the printing device raised up to give access tothe type and other parts contained within its case; Fig. 4, a section inline Y Y of Fig. 3, with the printing device in working position andshowing the means for holding the inking -roller in contact with theprinting-roller; Fig. 5, an enlarged perspective detail oftheextensionbracket for holding the guide-roller and the impression-cylinder; Fig. 6, a perspective view of the type-cylinder detached;Fig. 7, an enlarged perspective view of the typeholding channel-bar, andFig. 8 an enlarged perspective view of the type adapted to fit saidchannel-bar.

Referring now to the details of the drawings by letter, A designates theframe of any suitable or well-known wrapping-paper-roll holder,consisting of vertical supports a for the spindles b of the paper-rollB, and crossbars a, a to connect said supports and to which the printingdevice is attached.

The casing 1 of the printing attachment is half-round or lune-shaped andis adj ustably secured to pendulous rods 2, having loops 3 at theirupper ends to receive thumb-screws 4, fitted into the opposite ends of aclampin g-barv 5, the latter having jaws 6, the middle one of whichisfitted with a clamping thumbscrew 7 to hold the said clamping-bar 5securely to the cross-bar a of the frame of the paper roll holder. Theprinting device is thus securely held upon the frame to rest with thepressure of its weight only upon the paper-roll, thus allowing thelatter to turn freely. The rods 2 are made of tempered steel and aresecured to the casing by means of clamping-disks 8, secured centrallyupon bosses 9 on the outer sides and ends of the casting by means ofthumb-screws 10, which pass through the said disks and screw into thesaid bosses, the disks being preferably provided with notches upon theirinner faces to receive the rods 2, the latter being thus securely heldin any adjustable position upon the casing. The casing is madeadjustable upon the rods 2 for two reasons-first, to allow the printingdevice to be placed at any required distance from the clamping-bar toadapt itself to the paper-rolls of various diameters, and also todecrease or diminish the pressure of the type-,cylinderagainst theimpression -.cylinder in a novel manner, as follows:

The type-cylinder 1] is spool-shaped, the end disks 12 thereof rollingover the paper and holding it against an impression-cylinder l3,journaled in brackets 14:, fixedly supported upon, the ends of thecasing 1 and the reduced portion of the type-cylinder having suitablemeans for holding channel-bars 16, into which rubber type 17 are set upand securely held to press against the paper which is drawn between thetype-cylinder and the impression-cylinder. The ends of the shaft 18 ofthe type-cylinder passes through slots 19 in the ends of the casing 1,the said slots being directed toward the center oftheimpression-cylinder 13 and the shaft fitted with spools 20, thegrooves of which receive the lower ends of the tempered-steel rods2,which are caused to press againstthe said spools with any requireddegree of pressure bymeans of the clamping-disks 8, which securely holdthe rods after they have been drawn and bowed to the required tension topress the type-cylinder with sutficient force toward the theimpression-cylinder to make a clean imprint upon the paper. The brackets14, affixed to the ends of the casing, also carry a guide-roller 21,which rests upon and revolves at the same surface speed with thepaperroller and is also held parallel to the impression-cylinder toenable a clear imprint upon the paper in the event of the roll not beinground or the surface even.

The inner sides of the ends of the casing 1 have L-shaped grooves 22therein to receive the ends of the spindle 23 of the inking-roller 24,one arm of the groove being directed toward the axis of thetype-cylinder and the other arm of the groove leading to the edge of thecasing, thus to allow theinking-roller to be readily removed from orreplaced within the casing after the type-roller has been removedtherefrom. The inking-roller is held to press against the type-roller bymeans of springs 25, secured at one end to eyebolts 26, screwed into theends of the casing from the inner sides thereof, the said springs beingbowed around the ink roller spindle and adapted to press with their freeends thereon to hold the said roller to bear with the required pressureupon the type-roller. It will thus appear that the printing device willalways preserve an easily-regulated and constant adjustment both toproperly ink the type and to press the type against the paper with anyrequired degree of pressure which will not be interferred with by theconstantlydiminishing diameter of the paper-roll or the strain ortension upon the paper when it is drawn from the roll. The paper willalways roll off evenly from the roll, having first to pass between thetype-cylinder and the impression-cylinder to the cutter or knife.

The brackets 14 are preferably made in adjustable sections, as shown inFig. 5, to adapt them to receive the impression-cylinder 13 andguide-roller 21 of any required lengths to suit the width of thepaper-roll. The type can be set in the cylinder or removed therefrom atany time without removing it by turning the casing up, as shown in Fig.3 of the drawings.

The channel-bars 16, which receive the type 17, are secured by screwswhich pass through lugs 27, upon the ends of the channel-bars and screwinto the type-cylinder and are made with outwardly-converging sides toreceive and thus securely hold the type 17, the latter being formed, asshown in Fig. 8, with correspondingly-inclined or dovetailed sides tofit the said channel-bars.

The invention can be made, as described above, with rollers 13 and 21 orwithout them when the impression-cylinder will rest upon the roll and asthe paper is drawn will cause the impression-cylinder, Fig. 6, torevolve.

I claim as my invention and desire to secure by Letters Patent 1. Thecombination with a paper-roll and a supporting-frame thereof, of abracket clamped to the top of the frame and provided withrearwardly-directed and pivotally-supported spring-arms, a casingadjustably secured on said spring-arms adapted to swing up over saidsupporting-frame, a spring-pressed ink-roll in said casing, aprinting-roll also journaled in the casing, and a bracket engaged oneach end of the casing, a plurality of rollers journaled thereon one ofwhich engages against the paper-roll and another of which is journaledto receive the pressure from the printing-roll, and between which andthe printing-roll the paper is passed as it is drawn from the roll.

2. In a printing attachment for paper-rolls the combination with acasing, of a transverse slot in the ends thereof, a laterally andupwardly extendinggroove on the inner surface of the ends of saidcasing, a shaft movable in and projecting through said slots, atype-cylinder rigidly fixed thereon, an inking-cylinder movably fixed insaid grooves, a paper-roll holder, spring-rods pivotally securedthereon, adjustably secured to the ends of the easing and bowed to pressagainst the type-cylinder shaft.

3. In aprinting attachment for paper-rolls, the combination with thepaper-roll frame adapted to hold a roll of paper therein, of a casingyieldingly supported from the frame in operative relation with the rollof paper, a type-cylinder and an inking-cylinder journaled in saidcasing, brackets secured to and projecting outwardly from the ends ofthe casing and an impression-cylinder journaled on the brackets, andover which the paper is drawn, and a roll also journaled on the bracketsand adapted to track on the paper-roll when in operation, said casingbeing adapted to swing upwardly and rest in an inverted .position uponsaid frame to enable the adber, 1899.
